Yes and yes. You usually have to click on a link on the web page and a download manager is initiated. It will ask whether you want to run it from the original loaction or save to disk (do the latter and save it to the desktop so you can find it easily). Once downloaded it will ask whether you want to "open" (or run the program) or not. If you run it it will usually go through an installation wizard in which you most often just click yes (OK) to everything. If not then you can install the application (again via a wizard)by simply double clicking it (remember its on your desktop).
